This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. This standard is one of a series of standards for evaluating the contribution to the fire resistance of structural members by applied fire protection materials. The other parts of this series are: — Part 2: Vertical protective membranes, — Part 3: Applied protection to concrete members, — Part 4: Applied passive protection to steel members, — Part 5: Applied protection to concrete/profiled sheet steel composite members, — Part 6: Applied protection to concrete filled hollow steel columns, — Part 7: Applied protection to timber members, — Part 8: Applied reactive protection to steel members. The fire protection capacity of the horizontal protective membrane can be nullified by the presence of combustible materials in the cavity above the membrane. The applicability of the results of the assessment is limited according to the quantity and position of such combustible materials within that cavity. The amount of combustible material permissible in the cavity should be given in national regulations. Caution: The attention of all persons concerned with managing and carrying out this fire resistance test, is drawn to the fact that fire testing can be hazardous and that there is a possibility that toxic and/or harmful smoke and gases can be evolved during the test. Mechanical and operational hazards can also arise during the construction of test elements or structures, their testing and the disposal of test residues. SIST EN 13381-1:2014

Scope This European Standard specifies a test method for determining the ability of a horizontal protective membrane, when used as a fire resistant barrier, to contribute to the fire resistance of standard horizontal structural building members as defined in 6.4.2. Test of horizontal protective membrane installed under a specific non-standard floor should be tested according to EN 1365-2. This European Standard contains the fire test which specifies the tests which are carried out whereby the horizontal protective membrane, together with the structural member to be protected, is exposed to a fire test according to the procedures defined herein. The fire exposure, to the temperature/time curve given in EN 1363-1, is applied from below the membrane itself. The test method makes provision, through specified optional additional procedures, for the collection of data which can be used as direct input to the calculation of fire resistance according to the processes given within EN 1992-1-2, EN 1993-1-2, EN 1994-1-2 and EN 1995-1-2. This European Standard also contains the assessment which provides information relative to the analysis of the test data and gives guidance for the interpretation of the results of the fire test, in terms of loadbearing capacity criteria of the protected horizontal structural member. In special circumstances, where specified in national building regulations, there can be a need to subject the protection material to a smouldering curve. The test for this and the special circumstances for its use are detailed in Annex C. The limits of applicability of the results of the assessment arising from the fire test are defined, together with permitted direct application of the results to different structures, membranes and fittings. This European Standard applies only where there is a gap and a cavity between the horizontal protective membrane and the structural building member. Otherwise, the test methods in prEN 13381-3, EN 13381-4 or prEN 13381-5, as appropriate, apply. Tests should be carried out without additional combustible materials in the cavity. Annex A gives details of assessing the performance of the ceiling when exposed to a semi-natural fire. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
